Seria1 No. 471,946.

T o all whom tt may concern:

Be it known that I, LAzARUs L. RANDLE, a citizen of the United States,residing at Muldon, in the county of Monroe, State of Mississippi, haveinvented certain new and useful Improvements in Vent-ilators; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the saine.

This invention relates to ventilators; and has for its object to providea simple and efficient device for Ventilating stacked vegetablesubstances, such as hay, green cut corn, alfalfa, straw, et cetera, whendamp or when not fully cured for the purpose of protecting the materialfrom heating, molding, or rotting.

To this end, the invention consists of the construction and peculiar'arrangement of certain pipes to be placed in a slack, as will behereinafter more fully described and pointed out in the appended claim,and illustrated in the accompanying drawings, in which- Figure l is anelevation of the Ventilating device; Fig. 2, a plan view of the samewith the ventilating cap removed; Fig. 3, a perspective view,illustrating a detailed con struction.

Similar reference characters indicate the same parts throughout thefigures.

In the drawings, l indicates a pipe union having in this instance fourprojecting arms 2 radiating from the center of said union in ahorizontal plane, said arms being disposed at right angles to eachother. From the top of the union there projects vertically another arm3, to which a vertical trunk pipe 4- is separably connected. Air inletpipes 5 are connected to the radiating arms 2 of the union forming acruciform base which supports the device. Each of these pipes is made ofa plurality of separable sections G connected together preferably byslip joints similar to stove pipe connections, so that they may beeasily connected or disconnected when the ventilator-is erected or takenapart. Said sections are provided each with a number of perforationsthrough which air`may enter from the material piled thereon and passalong the horizontal pipes to the union and thence up the vertical trunk4L to the top Where it escapes. The outer ends of each horizontal pipeare enlarged or made trumpet shape to give ready access to air for thepurpose of creating a draft through therventilator. The several parts ofthe device are preferably formed of sheet metal, such as galvanizediron, as this material is cheap, strong and will readily withstand theeffects of moisture without deterioration. The union l may also beperforated in a manner similar to the pipe sections as represented inFig. 3.

Une method of erecting the ventilator is as follows: The union l isfirst placed on the ground or upon a suilicient quantity of hay or othermaterial to be stacked, to raise the outer bell-mouthed ends above theground. The pipes 5 are then connected t0- gether, as many sectionsbeing used as desired or required by the diameter or other measurei'nentof the stack or rick, it being preferred to have the open mouths ofthese pipes very near, if not actually projecting beyond the outside ot'the stack. 'lhe pipes after being made the proper length are thenslipped over or into the arms 2 of the union l, until they lit tightly.The trunk pipe i is assembled by joining the separable sections 7 whichare preferably larger than the section (i, until it has reached asuitable height. Instead of completing the pipe and then connecting itto the union, it may be built up a section at a time as the material :ispiled and when raised as high as necessary, the upper end is providedwith a ventilating cap 8 of any approved construction. From this, itwill be seen that the ventilator 4 is situated in the center of thestack or rick and should there be any heat-ing of the hay or othermaterial, of which said stack is formed, air in the trunk 4; will beheated and rise therein, escaping from the top, thereby causing' coldair to enter the horizontal pipes 5 through their ends and through theperforations 9 in the pipe sections and also through similarperfor-ations in the trunk pipe 4, air being drawn through the stackedmaterial to enter said pcrforations, thereby drawing it and at the sametime reducing its temperature. Although the stack may not be heated,there will be a normal circlilation of air through the pipes and thestack.

The device is simple, easily taken apart for the purpose of storage, andas easily assembled when it is to be erected.

lVhat is claimed is:

A ventilator of the class described comprising a central hollow pipeunion having radially projecting tubular branches disl hood mounted atthe uppermost free end of posed in the same plane and a vertical tubuthelast named tube.
